Abstract

We have cloned a genomic fragment of Candida albicans by complementation of a Saccharomyces cerevisiae cyr1 mutant. This fragment contains the two-thirds C-terminal part of the adenylate cyclase CaCYR1. The complete gene has been sequenced from PCR fragments amplified from genomic DNA, and contains an ORF of 1690 amino acids closely related to other fungal adenylate cyclases. Adjacent to the adenylate cyclase gene, we have sequenced six other putative genes. CaCHS6, CaYNL191 and CaYJL098 are named on the basis of their close similarity with S. cerevisiae genes. ORFs CaYJL097a and CaYJL097b represent two repeated homologues of the S. cerevisiae YJL097w, which probably arose from an ancient duplication. The last one is a hypothetical ORF, CaYKR049, which presents only a very weak similarity with YKR049. The S. cerevisiae homologues of three of these genes are co-localized on chromosome X but with a different order and orientation.
